I take klonopin at night to help reduce anxiety so I can sleep (used to take Xanax but ODed on it when I went through an intense emotional crisis & ended up in the ER). I tried taking the klonopin once during the day when I was very anxious, but it just made me so tired. I don't want to sleep through my days. I just ride through the anxiety during the day. I never abused the Xanax though I was on it for 17 years. I just had a bad depressive episode (bipolar 1) & acted rashly & took a bunch of them. Doing better now. Trying to regain the stability I had before.--Suzy
